1. INSTALLATION 1.1 Mounting the Loud Hailer The Loud Hailer can be mounted on a desktop, on the overhead, on a bulkhead or flush mounted in a panel (optional kit required). Refer to the mounting template (supplied) for installation instructions. Mounting considerations When planning the location for the Loud Hailer, keep in the mind the following considerations. Locate the unit where the front panel can be easily viewed and operated.
1. INSTALLATION Flush mounting Requires flush mount kit LH-3020 (Code No. 000-149-112). See the flush mount outline drawing for details. Contents of flush mount kit 1. 2. 3. 4. 5. Name Type Code No. Flush Mounting Plate TZ7300012A 999-999-025 2 Screw 6X12 SUS304 999-999-027 2 Wing Screw M4X35 SUS304 999-999-027 4 Wing Nut M4 SUS304 999-999-028 4 Make a cutout in the mounting location referring to flush mount outline drawing. Place the Loud Hailer in the cutout.
1. INSTALLATION 1.2 Intercom Speaker (option) Four intercom speakers (maximum) may be connected to get 2-way communications between master station and one or all intercom speakers. For mounting dimensions and fixing instructions, see the outline drawing.
1. INSTALLATION 1.3 Wiring All equipment are terminated at the rear panel of the LH-3000. See the illustration on the next page for how to connect equipment to terminals. Refer to the interconnection diagram for detailed information. Rear panel layout 13.
1. INSTALLATION Wiring The illustration below shows how to connect the power supply. Other equipm ent are connected similarly. (1) Unfasten screws. J1 J2 J3 (4) Set terminal; tighten screws. - + AFT - + FWD Jeweler's screwdriver (2) Pull out terminal. - + 13.6V (3) Insert wire into terminal, and tighten screw at top of terminal. - Note 1 : Connect power cables to the battery correctly.
1. INSTALLATION Power connection 77 3 The LH-3000 is intended for Sheath Armor use with a 13.6 VDC power Drain wire fabrication supply. Connect the power L* Armor * Length long enough to reach ground terminal. cable (loca l supply) to the 5 15 Sheath terminals labeled “13.6V”. φ = 11.7 mm Use cable type DPYC-1.5 or Conductor Cut the sheath. S = 1.5 mm 2 equi v alent. Fabricate the φ = 1.56 mm Solder drain wire DPYC-1.5 Sectional view cable as shown below.
1. INSTALLATION Hailer horn (local supply) Mount the hailer horns (local supply) facing away from the Loud Hailer to prevent feedback. They should also be pointed in the opposite direction of the microphone as you are speaking into it. Before mounting any horn, you should test it with the HAIL feature with the horn in the desired location to check for suitability of mounting location. Connect horns to the Loud Hailer with cable type DPYC-1.5 or equivalent. (See page 6 for how to fabricate this cable.
1. INSTALLATION Floating ground The LH-3000 has a floating ground. What this means is that the heat sink ground is floating and will not ground batteries if they are connected to the ship’s chassis. To maintain a floating ground: 1. Use a stereo plug when connecting a 4 ohm speaker to the external speaker plug. Connect it as shown in the illustration below. Do not use for battery use for ship's earth only Stereo plug 2. Do not connect any of the output connectors on the rear panel to the ship’s ground.
